In the process industries, stiction is the most common performance-limiting valve problem and over the last decade numerous different techniques for overcoming it have been proposed. This book represents a comprehensive presentation of these methods, including their principles, assumptions, strengths and drawbacks. Guidelines and working procedures are provided for the implementation of each method and MATLABAr-based software can be downloaded from www.ualberta.ca/~bhuang/stiction-book enabling readers to apply the methods to their own data. Methods for the limitation of stiction effects are proposed within the general context of: oscillation detection in control loops, stiction detection, diagnosis and stiction quantification and diagnosis of multiple faults. The state-of-the-art algorithms presented in this book are demonstrated and compared in industrial case studies of diverse origin a chemicals, building, mining, pulp and paper, mineral and metal processing.A common scenario is that a method is proven theoretically and rigorously tested in simulation, but then fails to get adopted in ... Robustness and reliability turn out to be crucial elements in gaining acceptance of any new technology in most ... Moreover, such valves are employed in combination with hydraulic cylinders.
